Specification of Letters Patent.

Patented Oct. 16, 1906.

Application filed January 19, 1906. Serial No. 296,861.

T0 (1, whom it may concern: I

Be it known that I, WILLIAM GADD, a subject of the King of Great Britain, residing at 64 Barton Arcade, Manchester, in the county of Lancaster, England, have invented new and useful Improvements in Columnless Gas- I-Iolders Supported by Helical Guides, (for which I have made application for patent in Great Britain with provisional specification No. 24,899, bearing date ofDecember 1, 1905,) of which the following is a specification.

e improvements relate to columnless gas-holders which are supported during their ascent and descent by means of helical guides and the object of the invention is to give to and fall in lieu of the screw-like or helical motion obtained with ordinary helically-guided gas-holders. Furthermore, the present invention forms a modification in construction of an invention for controlling gas-holders Which is the subject of an application for patent in the United States previously filed by me under the same title as the present.

0 accomplish this and to effect my improvements, I mount the helical guides on the vertical sides of the tank in the case of single-lift gas-holders, or on the inside of the lower lift in multiple-lift gas-holders, in a manner similar to what has heretofore, to

some extent, been arranged, and, in addition, vertical guides are employed, as many as may be found requisite, to prevent the turning movement due to the friction of the helical guides. The present vertical stays may be utilized to form the vertical guides aforesaid when desirable. The guide-rollers into which the helical guides take instead of being arranged as fixtures or resistance-points, as in ordinary helically-guided holders, are attached to a ring or band of suitable formation capable of moving horizontallyaround the circle in such rises and falls vertically the helical guides give a horizontal circular motion to such ring instead of a helical motion to the holder itself. Nevertheless this ring, traveling horizontally in suitable bearings or supports, firmly and securely grips or holds the holder at all heights and yet enables the holder to rise and fall vertically, thus obviating any inconvenience which in some cases may possibly ensue from the screw-like or helical rise and fall which is characteristic of the ordinary helically-guided gas-holder but that the manner that as the holder will, with the aid of the accompanying drawings, proceed to more fully describe means employed by me.

Figure 1 is a View in improvements maybe better understood I elevation, part thereof belng shown in section, of a portion of a gas-holder; and Fig. 2 is a sectional elevation of portions of the gas-holder and tank-wall, while Fig. 3 is .a plan, on a smaller scale, of the said portions of a gas holder and tankwall, all arranged according to my invention.

trating adaptations of the invention to the inner and outer lifts of telescopic gas-holders. (1, represents the wall of the gas-holder ank, which tank, as is well known, forms what may be termed a socket for the re ception of the gas-holder. The tank-wall is omitted from Fig. 1 for the sake of clearness, and 0 represents guide-rails mounted thereon in helical form, while is represents vertical guides, also attached to such tank-Wall.

b is the gas-holder bell, and (Z represents the rollers for engaging with the rails c, which rollers in ordinary helically-guided gas-holders are arranged as fixtures or resistancep0ints, but which in accordance with my present improvements are attached to a ring or band 6, capable of moving horizontally around the circle. Antifrictionrollers h are shown provided upon the gasholder 5 for supporting the ring or band 6 and for allowing the same to freely move in a circular path when necessary. These rollers h are in Fig. 2 attached to the gas-holder near the bottom thereof, in Fig. 4 they are mounted uponthe side of the cup of an upper lift, and in Fig. 5 they are mounted beneath such cup, the rollers in the latter case projecting within a ring 6, of channel section, which is here employed in lieu of the flat band a of Figs. 1 to 4.

The rollers 61 upon the ring or band 6 engage with the helical rails c, and thus enable the holder to be securely gripped or held at all heights of its rise and fall.

The vertical guides 75, in number as may be found requisite, take into guide-rollers, such as Z, mounted on the gas-holder (on the up per lift in Figs. 4 and 5) for the purpose of preventing the turning movement of the holder, due to the friction of the helical rail 0, and to cause such holder to take a vertical rise and fall. I

In Figs. 4 and 5 the vertical guides in and helical rails c are shown attached to the in- F lgs. 4 and 5 show sectional elevations illusside of the outer lift of the gas-holder, which outer lift may in its turn be described as a socket for the reception of the remainder of the gas-holder, while the rollers Z and h are, as described in connection with the cupping or dip portion of the inner lift of the gas-holder, for telescoping purposes.

- In operation it will be seen that as the gasholder rises or falls it is prevented from turning by reason of the vertical guides k engaging nation of the helical guides 0, taking into the rollers (I, will while the holder is in motion impart a circular movement to the band or ring e, by which means the holder will be firmly held at all working heights, any tilting of the holder being prevented'by reason of the ring a enabling all lateral pressures to be resisted at the gripping-points around the circle.

with the fixed rollers l, but that the inclil In gas-holders sup orted by helical guides,

a ring free to move iorlzontally about a periphery of the gas-holder, antifriction-rollers supporting and guiding said ring and mounted on the gas-holder, guide-rollers mounted on said ring, helical rails taking into said guiderollers and mounted on the socket within which the gas-holder carrying the ring rises and falls, vertical rails mounted on said socket, and guiderollers taking into said vertical rails and mounted on the gas-holder, substantially as set forth.

WILLIAM GADD.
